Tliat he possessed a head and a face not unlike that of an ape witii a brain consider- ably larger than that of an\ known simian, there seems to be no doubt. Concerning the detailed organization ol this earliest iorerunner ol the human raet', little can be said since his discoverer. Dr. Eugen Dubois, was fortunate enough only to recover several teeth, a portion ol the calvarium and one femur. From these fossil remains, however, Dubois has maintained, and other authorities unanimously sustain his argument, that Pithecanthro- pus erectus, by virtue of the size and shape of his femur, must have assumed the erect j)ostLire. He was thus able to ualk upon both feet much in the man- ner of his modern successors. It is also probable that m stature this primiti\'c man was not greatly inferior to the |)reseiit human races. That he employed his hands in the use of weapons and certain crude implements, that his life depended mainly u|)on recourse to primitive means for protecting him- self against the numerous enemies w hich beset his ])ath and lay in wait about his camping places, seems more than likely, hlis time was doubtless so fully preempted by the arduous tasks of gaining sustenance for himself, that little remained for the more leisurely production of ancillary industries or cul- tural pursuits. So closely was this human creature related to his contemporaries in the animal kingdom that he managed to hold his position among them only by a narrow margin of superiority. This slight ascendancy was derived Irom a d
